Delhivery — Regarding non delivered parcel

I lost my phone number which was used while providing the address. But my adress was very clear and everyone in my locality knows me very well. If the delivery person tried to deliver the product I would have easily got my product even without contact number. There is no customer care number or support contact. Now the product is getting returned to seller. Now I have to pay extra money for reshipping. I want a companion, Apology as well as reform to the customer support in the company.
